Specification of Letters Patent.

Patented May 5, 1908.

Application filed June 18, 1907- Serial No. 378,778.

T all whom it may concern:

Beit known that l, Josnrn F. Mines, a citizen of the United States, residing at Paris, in the county of Lerner and State of Texas,

r have invented certain new and useful Inito a smoke stack whereby the soot and other products of combustion will be caught while passing through the arrester, means being provided whereby the soot may be removed from the arresting devices and conducted to the bottom of the arrester, where it is removed through suitable openings provided therefor.

With this object in view, the invention consists of certain novel features oi construction, combination and arrangements of parts as will be more fully (,lescribed and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a vertical sectional View showing the invention applied to a stack which is provided with a forced draft; Fig. 2 is a horizontal sectional view of the same; and Fig. 3 is a View similar to Fig. 1, showing the invention applied to a flue or chimney of a building.

Referring more particularly tothe drawings, 1 denotes the arrester, in which is arranged in a zig-zag manner a series of semicircularbafile plates, 2, which provide a tertuous passage from the lower to the upper end of the arrester, as shown. Revolubly mounted in suitable bearing brackets, 3, arranged in the upper and lower ends of the arrester is a centrally disposed shaft, 4, on which is secured a series of radially projecting cleanii'ig blades, 5, one of said blades being arranged between each of the baflle plates, 2. The blades 5 are of such size that their opposite ends will come into close )IOX- imity to the upper side of one of the plates, and their up )6! ends into close proximity to the undersi e of the next ad acent plate, while the outer edge of the blades comes into close proximity to the inner wall of the arrester, whereby when the shaft 4 is revolved,

the blades .5 will be moved over or across the baffle plates and around the inner wall of the arrester, thereby scraping or cleaning or). all of the soot or other products of combustion which may have accumulated thereon.

Arranged adj acont to one side of the arrester is an upwardly projecting water conductin pipe, 6, the upper end of which is arranger to discharge water into a distributing trough, 7, which is disposed in the upper end of the arrester, as shown. The trough 7 is provided in one side with a series of notches 8, through which the water from the trough is adapted to overflow, and by means 01 which the water will be distributed across the upper baille plate, from whence it will run ofi' over the inner edge and onto the next lower plate on the opposite side of the arrester. At the lower end of the arrester on the opposite side from the lowermost balile plate is arranged a watcr-receiving trough, 9, into which the water from said lower plate is discharged.

The trough 9 is provided withadischarge tube 10 which projects through the side of the arrester and carries oil' the water from the same. In passing through the arrester, some of the water is absorbed by the soot and other products of combustion, so that the same will be heavier than the air, and will consequcntly fall upon the baffle plates from which it will be removed by the cleaning blades upon the turning of the shaft, 4. Any suitable means may be provided for turning or oscillating the shaft 4, the same being shown in the rcscnt instance as provided with a cran handle, 12, secured tl'icreto ad acent to its lower end.

in Fig. 1 ol the drawings, the arrester is shown as having connected to its lower end a smoke-conducting ipc 13, which extends from the smoke stacii below a damper, not shown. In the ipo 125 is arranged a fan, 14, by means of w rich a draft is provided to force the smoke through the tortuous passage around thc baffle plates of the arrester. The shaft ol the fan 14 projects through the lower side of the pipe 13 and is mounted at its lower end in a suitable bearing bracket 16, and is provided with a drive pulley, 17, with which is adapted to be engaged an operating belt. The up or end of the shaft 15 is mounted in a brac et 18, arranged in the pipe 13, and said u per bracket 18 is kept cool b r a current 0 cold air which is conductec thereto through a tube 19 arranged around the shaft 15, as shown. The lower end of the tube 19 o ens throu h the lower side of the pipe so t at when t 1e fan is revolved, a current of cold air will be drawn in through the tube to the bearing bracket 18, thus preventing the same from becoming overheated by the smoke when passing through the ipe 13. to the arrester.

In order t at the soot and other matter which has been cleaned off the baffle plates and discharged through the lower end of the arrester may be removerhl rovide a series of clean-out doors, 20, WlllOl are arranged in-the lower end of the arrests-r and in the pi e 13, as shown.

Fig. 3 oi'the drawings the invention.

is shown as applied to a flue or chimney of a,

building in which the natural draft of the chimney below forces the smoke through the arrester. To the lower end of the arrester shown in this figure is connected the upper end of a smoke conducting pipe 21, which v extends into the building in. position to rei I claim as new and desire to seci re by Lettors-Patent, is:

, manner through the arrester,

-1. A smoke and soot arrester, comprising aseries ol trifle plates arranged in a zi -zag a revolubly mounted cleaning mechanism equi ped with a like arrangement of plates with t eirupper and lower edges adapted to remove 'the soot and products of combustion from said plates, and means whereby water is discharged onto the bafile plates, substantially a'sdescribed.

2. A smoke and soot arrester for stacks BEST AVAILABLE COPY senses comprising a series of baifie plates arranged in a zig-za manner through the arrester, a shaft series of cleaning blades secured to said shaft, and also arranged in a like manner, with their upper and lower ed es having a scraping action u on said ba e plates and means to force t e soot and other solid matter through the arrester, substantially as described.

A smoke and soot arrester for stacks, comprising a series-of baflie plates arranged in a zig-zag manner through the arresterfia smoke conducting pipe connected to the lower end of the arrester, a draft fan revolu'-' bly mounted in said pipe, a shaft revolubly mounted in said arrester, and a series ofcleaning blades mounted on said shaft to engage said baffle plates and the inner sides of the arrester, substantially as described.

4. A smoke and soot arrester having ar ranged at its lower end clean-out doors, a series of semi-circular baffle plates arranged revolubiy mounted in said stack, a,

first on one side and then on the other in an alternate manner through the arrester, a

cleaningshaft revolubly mounted in the are roster, a series of radially projecting cleaning blades secured to said shaitand adapted to engage said bafiie plates and the inner sides of the arrester, a crank-handle connected to said shaft, a water distributing trough arranged in the u per end of the arrester, said trough having ormed in one side a series ofdischarge notches, a receiving trough at the lower end of thearrester, a discharge'tube connected with said trough-and a water supply pipe arranged on the arrester and adapt ed to dischargewater into the trough at theup er end thereof, substantially as described. n testimony whereof I have hereunto set my-hand in presence of two subscribing Witnesses.
